“…245 Furthermore, disulfide bonds present as defects in the g-C3N4 framework because NH4HSO4 is used as a critical adjuvant during the preparation process could endow g-C3N4 nanosheets with partial biodegradability, permitting to the reducing responsive intracellular compartments to break disulfide bond. 246 Inversely, bulk g-C3N4 is very resistant to degradation. These results demonstrate that size and chemical modifications are playing an important role to improve g-C3N4 biodegradation.…”

Graphitic carbon nitride (g-CN) based nanostructures are distinctive materials with unique compositional, structural, optical, and electronic properties with exceptional band structure, moderate surface area, and exceptional thermal and chemical stability. Because of these properties, g-CN based nanomaterials have shown promising applications and higher performance in the biological avenue. This review covers the stateof-the-art synthetic strategies used for the preparation of the materials, the basic structure, and a panorama of different optimization strategies leading to improved physicochemical properties responsible for the biological application. The following sections include the recent progress in the use of g-CN based nanobiomaterials for biosensors, bioimaging, photodynamic therapy, drug delivery, chemotherapy, and the antimicrobial segment. Furthermore, we have summarized the role and evaluation of biosafety and biocompatibility of the material. Finally, the unresolved issues, plausible challenges, current status, and future perspectives for the development and design of g-CN have been summarized and are expected to promote a clinical path for the medical sector and human well-being.

“…g-C 3 N 4 is a metal-free polymeric semiconductor which can be readily prepared via a series of polycondensation reactions under mild conditions using low-cost carbon and nitrogen precursors. The structure comprises the replicated s -triazine units, with a band gap of 2.7 eV, thus enabling the material to be used as a photocatalyst. − Unfortunately, the photocatalytic activity of g-C 3 N 4 is limited by its low surface area, poor conductivity, fast photoinduced exciton recombination rate, narrow light absorption range, inadequate donor concentration, and low self-light harvesting ability. To circumvent these disadvantages, researchers have come up with initiatives such as synthesizing two-dimensional (2D), conjugated, nitrogen-rich functionalizations and/or doping with heteroatoms, mesopores, and co-catalyst-based carbon nitrides.…”

The emerging metal-free carbon nitride (C3N4) offers prominent possibilities for realizing the highly effective hydrogen evolution reaction (HER). However, its poor surface conductivity and insufficient catalytic sites hinder the HER performance. Herein, a one-dimensional vermicular rope-like graphitic carbon nitride nanostructure is demonstrated that consists of multichannel tubular pores and high nitrogen content, which is fabricated through a cost-effective approach having the final stoichiometry g-C3N4.7 for HER application. The present g-C3N4.7 is unique owing to the presence of abundant channels for the diffusion process, modulated surface chemistry with rich-electroactive sites from N-electron lone pairs, greatly reduced recombination rate of photoexcited exciton pairs, and a high donor concentration (4.26 × 1017 cm3). The catalyst offers a visible-light-driven photocatalytic H2 evolution rate as high as 4910 μ mol h–1 g–1 with an apparent quantum yield of 14.07% at band gap absorption (2.59 eV, 479 nm) under 7.68 mW cm–2 illumination. The number of hydrogen gas molecules produced is 1.307 × 1015 s–1 cm–2, which remained constant for a minimum of 18 h of repeated cycling in the HER without any degradation of the catalyst. In density functional theory calculations, a significant change in the band offset is observed due to N doping into the system in favor of electron catalysis. The theoretical band gap of a monolayer of g-C3N4.7 was enormously reduced because of the presence of additional densities of states from the doped N atom inside the band gap. These impurity or donor bands are formed inside the band gap region, which ultimately enhance the hydrogen ion reduction reaction enormously.
